Product Description:

The DDC01.2-N050C-DS01-02-FW is a digital intelligent servo drive produced by Bosch Rexroth Indramat within the DDC Digital Intelligent Servo Drives series. Intended for motion-control machinery, it combines a SERCOS interface command module with internal regulation to power synchronous motors through digital servo feedback. In automated handling, packaging, and machine-tool axes, the drive converts incoming control commands into regulated motor current so speed and position remain aligned with the higher-level controller. Digital servo feedback lets the control loop correct deviations quickly during acceleration, deceleration, and load changes. The unit carries function code 01 and is supplied in Series 1, Version 2. An IP65 housing and standard cooling allow cabinet-free mounting near actuators.

For continuous operation, the unit provides a rated output current of 50 A, enabling up to 4 kW of mechanical load on the connected motor. Its internal bleeder dissipates regenerated energy at 0.25 kW continuously, protecting the DC link during overhauling cycles. The power stage draws 6 kVA from the mains, and switching devices modulate the output at a pulse frequency of 8 kHz to reduce torque ripple. This switching behavior supports smooth current control during speed transitions. Drive electronics and the cooling profile keep acoustic emission in the standard 50 A reduced-noise class. Safe operating temperature is maintained up to 55 °C when airflow is unobstructed.

Transient braking events can be absorbed at a peak bleeder capacity of 10 kW, and the maximum regenerated energy is 5 kWs. Operation is permitted up to an installation height of 1000 m without current derating, and the sealed enclosure limits dust and water ingress while the airflow path removes the specified 500 W of internal power loss. The drive has a total weight of 21 kg. Its architecture maintains stable current regulation during rapid speed changes, which helps the motor respond consistently in dynamic servo applications.
